LAMP-SUPPORT.

Specification f Letters Patent.

Patented Jan. 13, 1914.

Application filed March 17, 1913. Serial No. 754,720.

To all whom t may concern.'

Be it known that I, HARRY C. REAGAN, a citizen of the United States,residing in the Icity and county of Philadelphia, State of Pennsylvania,have invented a new and useful Lamp-Support, of which the following is aspecification.

This invention relates to lamp standards or supports and moreparticularly to a support for tubular incandescent filament lamps ortubular vacuum lamps without a filament and has for an object to providea support in the form of a stand or hanger which will carry one or morelights as desired.

It has for a further object to provide a lamp support wherein a lamp isremovably mounted therein and may be readily replaced by a new lamp incase of burning out or breaking through one cause or another.

It has for a further object to provide a lamp support wherein aplurality of lampsv are removably mounted, each being independentlycontrolled though forming a part of the same circuit.

It further consists of other novel features of construction, all aslwill be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings one form thereof which is at present preferred byme, since the same has been found in practice to givel satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement andv organization of these instrumentalities asherein shown and described.

' Figure 1 represents a sectional elevation of a lamp support embodyingmy invention. Fig. 2 represents a section on line -w of Fig. 1. Fig. 3'represents an enlarged detail in section of one of the movable terminalmembers. Fig. 4 represents a section on line of Fig. 3. Fig. 5represents a detail of a contact controlling device.

Similar numerals of reference indicate corresponding parts in thefigures. V

Referring to the drawings l designates a standard preferably of tubularform having the channel 2 centrally disposed thereof and communicatingwith outlet openings 3 which, as here shown, are radially arranged withrespect to the axis of the standard 1.

The upper end of the column 1 terminates in an enlarged head 4 carryinga yplurality of outwardly projecting arms 5 which are eachlongitudinally bored, as shown at G, in order to communicate with theaforesaid channel 2. In the presen-t instance, I employ four of thesearms 5 and each carries a receptacle 7 on the end thereof, the samebeing ixedly secured in any desired manner and having a socket 8 ofinsulating material therein, which has communication with the bore 6.Within the socket 8 there is a follower member 9 having a stem 10,suitably guided in an opening 11 of the receptacle 7, while around thestem 10 a spring 12 is wound which bears at one end against the socket-8 and at lts opposite end against the follower 9, so that the latter isnormally pressed outwardly. The several followers are each connected toan electrical conductor 13 and form respectively a terminal contact fora tubular lamp 14, one end of which is adapted to seat upon the springpressed contact in the socket 8. The opposite end ofthe lamp 14 iscarried by a receptacle 15 provided with a socket 16 of insulatingmaterial to form a seat for the end ofthe lamp 14 A |hold the clip 21out of contact with the lamp terminal 22 but when it is desired to lightthe lamp, the follower 20 is moved against the tension of the spring 25by certain .means consisting, in the present 1nstance, of a side facec'am 26 mounted on a spindle 27 which latter is secured to or forms partof a rotatable switch knob 28. In the present instance, this knob isshown as an ornamental base for the receptacle 15 which is apertured toreceive a bushing 29 forming the bearing for the spindle 27.

30 designates arms pivoted at 31 to brackets 32 of the standard 1, eachof said arms serving as a support for one of the receptacles 15. Thearms 30 are each provided with a passage for an electric conductor 34which .connects with the contact follower 20, as will l number to thearms 30 and connected at one end to the standard 1 and at the opposite.

end to an arm 30, the action thereof being to normally pull or hold thearms 30 toward.

the upper terminal 24, so that when lthe lamp 14 is inserted between thetwo terminals it will be firmly gripped and held in operative position.

36 designates a reflector preferably of tubular form, in order toencircle the column 1 and substantially of the shape of an in- .vertedcone having diverging, curved side surfaces, which serve to correctlyreflect the light and obtain the maximum lighting or illuminatingeffect.

37 designates an extension of the standard 1 having secured thereto athreaded stem 38, which in the present embodiment of my invention,passes through a deflector or shade 39, serving as a top to the lampsupport, the said top being held in place by means of the nut 40. Itwill, however, be understood that the extension 37 and its ladjuncts mayserve equally as well as a hanger to support the lamp adjuncts in casethe base 41 is dispensed with, the latter of course being used when thedevice takes the form of a stand lamp.

Referring now to the cam member 26 and its adjuncts, it will be. notedthat the follower 20 has its ends seated in recesses 42 of the socketmember 16 in order to prevent the said follower from rotating with thecam 26. It will thus be apparent that the follower 20 has a free slidingmovement and is actuated in one direction by the cam 26 'and in theopposite direction by the lspring 25. Thus a partial rotation of theknob 28 brings the cam 26 beneath the follower 2O and raises the clip 21into contact with the lamp terminal 22 to close the circuit and causelightfY ing of the lamp or lamps, while a continuation of the rotarymovement will release the follower 20 and it will be returned by thespring 25.

In the operation or assembling of the device,`the arms 30 are movedagainst the tension of the control springs 35 to afford a sufficientspace for the insertion of a lamp tube 14, one end of which is placed`in the socket 8 against the spring pressedfollower 9 and the oppositeend in the socket 16. The arm 30 is now released and the tension of thespring 35 causes the lamp tube to be gripped or irmlyheld between thetwo socket members and with the terminal 22 in the path of movement ofthe springV contact clip 21. The circuit may now be closed by a'turningmovement of the switch knob 28 and a lamp or lamps lighted as desired.

It will now be apparent that I have devised a complete, unitarystructure simple in construction, well adapted for the purpose intendedand embodying a novel supporting means for tubular lamps whereby thereplacement of broken or inoperative lamps may be accomplished withgreat facility and whereby the lamps are normally held in operativeposition by. a yielding means which insures at all times proper locationthereof.

It will further be apparent that each lamp may be independentlycontrolled, that is, either lighted or not regardless of the conditionsof the remaining lamps. Furthermore, it will be seen that the relationbetween the lamp or lamps and my novel reflecting device is such as tocause the light to be evenly diffused and with the maximum effect. Itwill also be apparent that the use of the novel supporting device is notnecessarily conned to tubular lamps having a filament but may operateequally as well for vacuum lamps operating without a filamenty and Itherefore do not wish to be limited to'any particular style or type oflamp.

It will now be apparent that I have devised a novel and usefulconstruction of a lamp support which embodies the features of advantageenumerated as desirable in the statement o-f the invention and the abovedescription and while I have, in the present instance, shown anddescribed a preferred embodiment thereof which has been found inpractice to give satisfactory and reliable results, it is to beunderstood that the same is susceptible of modification in variousparticulars without departing from the spirit or scopeof the inventionor sacrificing any of its advantages.
